To @ZZ whom t 'may concern.-

Be it known that I, OREsTEs S. BROWN, a citizen of the United States,residing at Milwaukee, county of Milwaukee, and State of Wisconsin, haveinvented new and useful Improvements in Shade-Rollers and SupportsTherefor, of which the following is a specification.

My invention relates to improvements in shade-rollers and supportstherefor, and pertains especially to that class of such devices in whichthe roller may be raised or lowered along the window-frame, the rollerbeing hung from the upper portion of the frame on flexiblesupporting-bands, which are wound up and unwound as the roller is raisedor lowered.

IIeretofore attempts have been made to produce a practical device ofthis character; but a difiiculty has been found in securing the desiredtension of the winding-springs and in arranging` the parts so thateither the shade or the roller may be adjusted without affecting theoperation of the other.

rIhe object of my invention is to provide a form of construction whichmay be easily controlled and in which the desired adjustment may bereadily secured in either the position of the roller or of the shadethereon and in which the tension of the winding-springs may be nicelyadjusted or readjusted at any time.

In the following description reference is had to the accompanyingdrawings, in which- Figure 1 is a front elevation showing the upperportion of a window equipped with my invention. Fig. 2 is a detailshowing a portion of the flexible supports and showing the roller inlongitudinal section with a central portion broken away.

Like parts are identiiied by the same reference characters in bothviews.

1 is a shade-roller provided with a tubular socket 2 at one end, whichis filled at the end of the roller by a cylindrical block 3, providedwith a hub 4, to which one end of a windingspring 5 is attached, asindicated at 6. The other end of the spring 5 is secured at 7 to astationary sleeve 8, which sleeve extends through an aperture in theblock 3 and in an end disk 9, which is secured to the block. The sleeve8 is provided with stop-collars 10 and 11 in each side of the disk 9,which hold the sleeve 8 and roller 1 against relative longitudinalmovement. A rod `13 extends through the sleeve 8 and through the solidportion 14 ofthe roller into a tubular recess 15 at the other end of theroller, and a stopcollar 16 is secured on the rod 13 in this recess toprevent the rod from slipping out through the sleeve 8. The disk 9 isprovided with a dog 18, adapted to engage in a suit-` with a tubularsocket 28, leading inwardlyl from the outer end of the cylinder andclosed by an end disk 30. A spring 31 within the socket is connected atone end with the disk 30, and the other end of the spring is connectedat 32 with a stationary rod 33. A pin 35 is rigidly secured to the endof the rod 33 and projects outwardly through a central aperture in thedisk 30 and through an aperture in a cylinder-head 36.

A winding-drum 40 is mounted upon and rigidly secured to a hub portionof the cylinder-head 36, the drum and cylinder 25 being thus rotated inunison and in connection with a similar drum 41, mounted upon andrigidly secured to the projecting end of the rod 13. Flexiblesupporting-bands 43 and 44 are connected with hooks 42 at the upperportion of the window-casing and are wound upon the drums 40 and 41,respectively. Guiding-arms 45 and 46 are rigidly secured to the pin 35and sleeve 8, respectively, and are provided with loops at 48, whichloosely engage the supporting-bands. These arms 45 and 46 prevent thepin 35 and sleeve 8 from rotating and also regulate the winding of thebands upon their respective drums.

The spring 31 tends to rotate the drums through the medium of thecylinder 25 and rod 13 in a manner to cause the supportingbands 43 and44 to wind upon the drums, and thus raise the shade-roller.. A dog 50,pivotally secured to the disk 30, is adapted to engage a suitable notchin a collar 51 on the pin 35 and when so engaged limits the rotation ofthe cylinder 25 and the drums, the operation of this dog being similarto that of the dog 18.

The springs 5 and 31 are of different ten- IOO TIO

the roller.

sions, the spring 31 being preferably stronger than the spring 5, sothat by pulling the shade 55 the roller 1 will turn to permit the shadeto unwind; as in the case of the shades in ordinary use. By releasingthis shade suddenly the reaction of spring 5 rotates the roller withsuch rapidity that the dog 18 is thrown out by centrifugal action andpermits l the shade to wind up.

The operation of adjusting the shade is pre-V cisely the same as if theroller were mounted on a fixed support. When it is desired to adjust theroller7 the latter is drawn downwardly by means of a cord 56, thesupporting-bands 43 and 44 being unwound l'rom the drums to permit thedownwardnmovement of When it is desired to raise the roller, the cord ispulled down sufficiently to cause the release of the dog 50, when byreleasing the cord quickly the reaction of' the spring 31 rotates thecylinder 25 with sufficient rapidity to prevent the rengagement of thedog 50, and the shade-roller will therefore be lifted by the action ofthe drums in winding the bands 43 and 44 thereon. The tension of eitherof the springs may be increased by releasing the correspondingguiding-arm 45 (or 46) from the band and using the arm as a lever torotate the otherwise stationary rod 33 (or sleeve S) until the spring isat the desired tension.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a device of the described class; the combination of ashade-roller, provided with tubular sockets in each end; an axialsupport for said roller, provided with winding-drums at each end of theroller; flexible supportingbands arranged to wind upon the said drums; aspring in one of said sockets and arranged to actuate the roller;another'spring in the other socket arranged to actuate the drums;suitable catches normally controlling the reaction of therespectivesprings and non-rotatable elements in said roller, each connected withone of the springs and provided with arms loosely engaging the bandsabove the drums.

2. In a device of the described class; the combination of a shade-rollerprovided with a tubular socket in one end; a hollow cylinder located insaid socket and projecting axially therefrom; a drum mounted upon theprojecting end of said cylinder; a supporting-band wound upon said drum;a journalpin loosely connected with the supportingband and constitutinga non-rotatable element mounted in said cylinder; vand a catch on saidcylinder adapted to engage said nonrotatable element together with aspring connected with said non-rotatable element; and also connected torotate said cylinder.
